Title: Removal of floating asbestos dust or the like
Inventor: TOKIMOTO NORITOSHI
IPC: E04F21/00
Filed: 1988-09-22
Abstract: PURPOSE:To make it possible to remove asbestos quickly and safely while eliminating a risk of the secondary pollution otherwise resulting from the treatment of asbestos by spraying a specified hardening solution over asbestos dust floating in air or adherent to the surrounding surface. CONSTITUTION:A hardening solution is obtained by mixing a solution of a water-soluble silicate (e.g., lithium silicate) of the formula (wherein M is an alkali metal belonging to Group IA of the periodic table); x is 2.0-4.5, and aq is an aqueous solution) with a synthetic resin emulsion and/or a water-soluble resin which does not cause shocking when mixed with the silicate and can form a film at room temperature in the presence of, optionally, a film-forming aid and, optionally, a pigment, a dispersant, a thickener, a film-forming aid, an antiseptic, etc. In performing a repair work such as confinement or removal of a coated asbestos layer in a building, the asbestos concentration in air is decreased by spraying the hardening solution over asbestos dust floating in a high concentration in the zone of treatment and the inside of the treated space and recovering the dust in the form of wetted asbestos.

Title: Camera and its preliminary method for photometory and equipment therefor and method
Inventor: ARAI MINORU
IPC: H04N5/351
Filed: 1992-08-17
Abstract: PURPOSE:To quickly decide the proper initial exposure value by deciding the initial exposure value to calculate the photometry value with the use of a 1st solid state electronic image pickup element based on the prescribed time stored by a 2nd solid state image pickup element. CONSTITUTION:When an AF module 20 is reset, the signal charge is stored in an AF CLD 21 synchronously with the fall of a clear signal XCLR. When the level of the detection signal received from a storage sensor 22 exceeds the threshold level of a comparator 23, a read request signal EOIS is judged that the signal charge of such an amount that can be AF-processed is stored in the fall AF CCD 21A and 21B. The storing time of the signal charge is stored in a CPU 3. When the signal EOIS falls down to an L level, the read start signal XS also falls down to an L level, Therefore the signal charge is given to the CPU 3 from the CCD 21, and the CPU 3 carries out the AF processing. When the storage of the signal charge is complete at both CCD 21A and 21B, the AE processing is carried out.

Title: Data recording/reproducing system
Inventor: SAKAMOTO AKITO
IPC: G11B20/16
Filed: 1987-09-24
Abstract: PURPOSE:To make self-clocking unnecessary and to simplify a modulating circuit and a demodulating circuit by recording a reference signal to a recording medium beforehand at frequencies sufficiently lower than that of a data signal, reading the reference signal from the recording medium and generating a clock signal. CONSTITUTION:A reference signal (b) is recorded beforehand at the frequencies of 1/N (N is a positive integer) of the maximum frequencies of the data signal to a recording medium 13. Thus, a reading signal (c) is generated and written so as to be synchronized with the reference signal (b) recorded to the recording medium 13 beforehand. Further, at the time of reading, a window pulse is generated according to the reference signal (b), in synchronization with it. Consequently, position deviation for the position of the window pulse and read data is hardly generated. Thus, the insertion of the clock signal into the data signal is made unnecessary, and the modulating circuit and the demodulating circuit can be simplified.

Title: Voice recognizing device
Inventor: UMEZAWA YOSHINAO
IPC: G06F3/16
Filed: 1990-09-12
Abstract: PURPOSE:To improve the efficiency of word reregistration and prevent a decline in word recognition rate by preferentially reregistering words from the word which has been wrongly recognized most frequently at the time of recognizing operations. CONSTITUTION:When an operation switch 6c is pressed in the case a word displayed on a display section 5 does not coincide with an inputted word, the adding section 11 of a wrongly recognized number holding section 3 adds '1' to the wrongly recognized number register of the relevant word following the instruction of a control section 1. Then a wrong recognition presence/absence discriminating section 20 selects a wrongly recognized word by referring to the register 10 as an object to be reregistered. Then an order adjusting section 21 sorts a word in the order of numbers of wrong recognized times. When a user inputs the sorted word in voice from a microphone 13, a voice recognizing section 4 performs a registering process. Since the registering process is performed in the order of the numbers of wrongly recognized times in such way, a decline in recognition rate can be prevented.
